Will the 390 Holley carb be a good choice for the stock motor? Will it also do ok if I decide to turbo it?
What about exhaust? It's 2.5" off the manifold then it appears to go to 2" and from the muffler it's 1-7/8" or 1.5" (haven't measured). Would it be fine to run 2.5" right through the muffler to the tip or should I drop to 2" after the muffler? I have read things about other engines needing the smaller exhaust pipe to help draw the exhaust away from the motor (i.e.: too big won't scavenge the exhaust). Regardless I will wrap the first few feet with header wrap to keep the heat down since the floor is aluminum and the exhaust heats it up pretty good.
Thanks for your help/advise.
Dave
